TechCrunch France has the scoop on the launch of the iPhone in France. The price is 300 euros, and it WILL NOT be a 3G phone. It will be exclusively available through Orange France.
The part that is really disappointing? There will be NO unlimited data plan available. That could get pretty pricey pretty quick.
No different than it would be in Canada, nothing says you get only 500MB a month like a bill for 200 bucks.
